Thanks, that's interesting.  I remember reading the original paper and 
didn't come across the explanation of the SOB/SOC (I thought it was 
earlier than that and the author wasn't Hanahan, but I could have been 
completely mistaken, I read it a long time ago.)

As for the bit about the SOB, I think it was from a former colleague of 
the original author who claimed he was a bit of SOB, making a joke of it.
